Abstract: A high-nitrogen ferritic heat-resisting steel comprises, in weight per cent, 0.01-0.30% C, 0.02-0.80% Si, 0.20-1.00% Mn, 8.00-13.00% Cr, 0.50-3.00% W, 0.005-1.00% Mo, 0.05-0.50% V, 0.02-0.12% Nb and 0.10-0.50% N and is controlled to include not more than 0.050% P, not more than 0.010% S and not more than 0.020% O, the balance being Fe and unavoidable impurities. The steel may optionally comprise (A) one or both of 0.01-1.00% Ta and 0.01-1.00% Hf and/or (B) or both of 0.0005-0.10% Zr and 0.01-0.10% Ti. A method of producing the steel comprises melting and equilibrating the steel components in an atmosphere of a mixed gas of a prescribed nitrogen partial pressure or nitrogen gas and thereafter casting or solidifying the melt in an atmosphere controlled to have a nitrogen partial pressure of not less than 1.0 ata and a total pressure of not less than 4.0 ata, with the relationship between the partial pressure p and the total pressure P.sub.t being10.sup.P <P.sub.t.sup.0.37 +log.sub.10 6.

Abstract: An apparatus for inserting transport anchors into a form for concrete parts comprises a magazine for feeding the anchors, and a gripper for removing anchors from the magazine and inserting the removed anchors into the form. The magazine orients a target anchor vertically, and jaws of the gripper close upon an end of the target anchor. The gripper is then rotated ninety degrees about a horizontal axis whereby the target anchor is removed from the magazine and reoriented to a horizontal position pointing toward the form. The gripper is then advanced transversely of the axis of insert the anchor into the form.
